so i had to buy the EDIMAX nMax wireless PCI Card so i could finally get internet on my G4. i installed the hardware and everything. im typing this using my neighbors crappy signal, which is all i could connect to. for some reason i cant connect to the router in my house. when i go to connect to a signal it lists my neighbors, my main computer downstairs, and another neighbors. i can connect to the main computer in my house and it says im connected but when i go to use firefox it says im not connected. can anyone help me figure out why i cant connect to my main computers wireless router??
